Interpreting Line Graphs #2

Front

What is a line graph?

Back

A line graph is a type of chart that displays information as a series of data points called 'markers' connected by straight line segments. It is used to visualize data trends over time.

Front

How do you determine the highest value on a line graph?

Back

To find the highest value on a line graph, look for the point that is the highest on the vertical axis (y-axis) at any given time on the horizontal axis (x-axis).

Front

What does the slope of a line in a line graph represent?

Back

The slope of a line in a line graph represents the rate of change between the two variables plotted on the axes. A steeper slope indicates a greater rate of change.

Front

How can you identify trends in a line graph?

Back

Trends in a line graph can be identified by observing the direction of the line over time. An upward trend indicates an increase, while a downward trend indicates a decrease.

Front

What does it mean if a line graph is flat?

Back

A flat line in a line graph indicates that there is no change in the value of the variable over the time period represented.

Front

How do you read the axes of a line graph?

Back

The horizontal axis (x-axis) typically represents the independent variable (e.g., time), while the vertical axis (y-axis) represents the dependent variable (e.g., quantity).

Front

What is the significance of data points on a line graph?

Back

Data points on a line graph represent specific values at a given time. They are plotted based on the coordinates derived from the values on the x and y axes.

Front

How can you compare two sets of data on a line graph?

Back

To compare two sets of data on a line graph, plot both sets on the same graph using different lines or colors, and analyze their trends and values over the same time period.

Front

What does an increase in the line graph indicate?

Back

An increase in the line graph indicates that the value of the dependent variable is rising over the time period represented.

Front

What does a decrease in the line graph indicate?

Back

A decrease in the line graph indicates that the value of the dependent variable is falling over the time period represented.
